Theories of Phonological Development11The preparation of this chapter benefited directly from work on the Stanford University Child Phonology Project, which is supported by National Science Foundation grants GS 2320 and GS 30962, for which grateful acknowledgement is made. We also express our appreciation for the work of Linda Kay Brown, who prepared the Bibliography. The Bibliography, in addition to listing those references used in text citations, includes an additional list that endeavors to provide a well-balanced basic bibliography on child phonology. For a more recent (but briefer) annotated bibliography, see Macken, M. L., Child phonology, Linguistic Reporter, 1974, 16(10), 9–12.
